When You're determining how much FPS a Desktop/Laptop can play at you look at the CPU and the GPU. In this case it's a laptop, I'm not familiar with a Laptop GPU so I have no clue as to the benchmarks, the processors are always clocked lower (for a laptop). I don't know Laptop GPU's, as I said, so can't really give you an accurate estimation...but if I had to guess I say playable FPS at around Med/High Settings (around 40 FPS). If you're looking to game why not get a Desktop? Unless this is going to be for portability reasons, I see no reason why not to get a desktop. The whole store, BestBuy, looks like a big jip...I mean no Desktop in the selections even have a decent GPU at prices of even $1,000!
I'd suggest you build a computer yourself and for $1,000 you could max out skyrim EASY, and BF3 with playable FPS.
